DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

Referring to FIG. 1 to FIG. 5, FIG. 1 to FIG. 5 are a 3-D appearance diagram, an exploded diagram and cross-sectional diagrams schematically showing a pen-type screen cleaner according to one embodiment of the present invention. As shown in the figures, according to one embodiment of the present invention, the pen-type screen cleaner includes a tubular shell 100, a rolled cleaning member 200 and a cleaning solution bottle 300.

The tubular shell 100 is formed from a first semi-tubular shell body 110 pivotally connected to a second semi-tubular shell body 120. In practice, the first semi-tubular shell body 110 has a first side 111 and a second side 112 opposite to the first side 111, and the second semi-tubular shell body 120 has a third side 121 and a fourth side 122 opposite to the third side 121, wherein the third side 121 of the second semi-tubular shell body 120 is engaged with the first side 111 of the first semi-tubular shell body 110, and the first side 111 and the third side 121 have a first axial hole 113 and a third axial hole 123 respectively. Two combination pins 170 are pivotally inserted into the first axial hole 113 and the third axial hole 123 from both ends of the third side 121. Accordingly, the first semi-tubular shell body 110 and the second semi-tubular shell body 120 are pivotally connected as one body about the combination pins 170 as an axis, and can be opposite and assembled to form the tubular shell 100 or disengaged as an open-shell case. In other words, the first side 111 and the third 121 form a pivotal-connection side, and the second side 112 and the fourth side 122 form an opening-closing side.

A recessed portion 114 is formed on the second side 112 of the first semi-tubular shell body 110, and an extensive cover portion 124 is formed on the fourth side 122 of the second semi-tubular shell body 120. When the first semi-tubular shell body 110 and the second semi-tubular shell body 120 are positioned opposite and assembled about the combination pin 170 as an axis, the extensive cover portion 124 of the second semi-tubular shell body 120 covers and engages with the recessed portion 114, thereby forming the tubular is shell 100.

A notch 115 and a protrusive plate 125 matched with each other are formed on the second side 112 of the first semi-tubular shell body 110 and the fourth side 122 of the second semi-tubular shell body 120 respectively, and there is a gap 180 existing between the notch 115 and the protrusive plate 125. Therefore, when the tubular shell 100 is desired to be lifted open, a user's finger may be advantageously inserted into the gap 180 to lift the protrusive plate 125, thereby disengaging the first semi-tubular shell body 110 from the second semi-tubular shell body 120 as the open-shell case.

A fastening unit 190 is disposed between the recessed portion 114 of the first semi-tubular shell body 110 and the extensive cover portion 124 of the second semi-tubular shell body 120. The fastening unit 190 includes a fastening body 191 formed on an exterior wall of the recessed portion 114, and a fastening groove 192 which is formed in an interior wall of the extensive cover portion 124 and is corresponding to the fastening body 191 in position. When the first semi-tubular shell body 110 and the second semi-tubular shell body 120 are positioned opposite and assembled about the combination pin 170 as an axis, the fastening body 191 and the fastening groove 1902 disposed at the opening-closing side are engaged with each other, thereby maintaining the tubular-shell case after combining the first and second semi-tubular shell bodies 110 and 120.

The tubular shell 100 has a first end 130 and second end 140 opposite to the first end 130, and a first receiving trough 150 and a second receiving trough 160 are disposed on the first end 130 and the second end 140 respectively.

The rolled cleaning member 200 is formed by rolling up a flat-type cleaning member such as a flat piece of cloth. The rolled cleaning member 200 is removablly received in the first receiving trough 150. Two stop ribs 151 are formed on an interior wall of the first receiving trough 150 and interfere with the rolled cleaning member, thereby preventing the rolled cleaning member 200 from falling off from the tubular shell 100.

The cleaning solution bottle 300 is removably received in the second receiving trough 160 of the tubular shell 100. When the cleaning solution bottle 300 is received in the second receiving trough 160, for maintaining its positioning stability, an embedded rib 161 is formed on an interior wall of the second receiving trough 160, and an embedded groove 310 is formed on an outer peripheral surface of the cleaning solution bottle 300 corresponding to the embedded rib 161 and is engaged with the embedded rib 161, thereby preventing the cleaning solution bottle 300 from falling off from the tubular shell 100.

The cleaning solution bottle 300 is a transparent bottle and has a bottle bottom portion 320 and a bottle mouth portion 330 opposite to the bottle bottom portion 320, wherein the bottle bottom portion 320 protrudes outwards from the second end 140 of the tubular shell 100, and thus the amount of cleaning solution existing in the cleaning solution bottle 300 can be directly observed from outside.

According to one embodiment of the present invention, the pen-type screen cleaner further includes a hanging clip 400 attached to the tubular shell 100 via a combining unit 410. In practice, the combining unit 400 includes a combining hole 411 formed on the second semi-tubular shell body 120, and a pair of wedge-shaped protrusions 412 are disposed on the hanging clip 400 for engaging with the combining hole 411, and thus the hanging clip 400 can be used to clip the tubular shell 100 on any proper position of a user, thus facilitating user portability.

Referring to FIG. 1 to FIG. 5 together with FIG. 6, when the pen-type screen cleaner of the present invention is desired to be used, as long as the second semi-tubular shell body 120 is lifted outwards at its protrusive plate 125 to release the engagement relationship between the fastening groove 192 and the fastening body 191, i.e. the first semi-tubular shell body 110 and the second semi-tubular shell body 120 are lifted outwards to be in the open-shell case about the combination pin 170 as an axis. Thereafter, the rolled cleaning member 200 and the cleaning solution bottle 300 can be taken out of the first receiving trough 150 and the second receiving trough 160 of the tubular shell 100 respectively, and the rolled cleaning member 200 can be flattened as a flat-type cleaning member, and then the cleaning solution bottle 300 and the flat-type cleaning member can be applied to clean a portable touch reading device 500.

After the portable touch reading device 500 is cleaned, the flat-type cleaning member is rolled up as the rolled cleaning member 200, and then the rolled cleaning member 200 and the cleaning solution bottle 300 are stored in the first receiving trough 150 and the second receiving trough 160 of the tubular shell 100 respectively. Thereafter, the first semi-tubular shell body 110 and the second semi-tubular shell body 120 are positioned opposite and assembled about the combination pin 170 as an axis, and meanwhile are fastened by engaging the fastening body 191 with the fastening groove 192, thus returning to the original pen-type receiving case.

According to one embodiment of the present invention, a pen-type screen cleaner is formed by rolling up the a flat-type cleaning member and then storing the rolled cleaning member and a cleaning solution bottle in both ends of a tubular shell, thus providing portable convenience; and the tubular shell has equipped with a hanging clip for being clipped on any proper position of a user for anytime anywhere access, thus facilitating user portability.
